My flightgear 1.9.1 worked fine then I installed the new version 2.4, didn't like so uninstalled and after that I have had problems with the zoom and that view change stopped working in the 1.9.1 version. I started playing around with the files and I got the view change working again via copying and overwriting some files, don't remember what ones, maybe view.nas.
Then I flew and made a major crash and after that when I closed the game and restarted the zooming and view change stopped working again and can't figure out what is wrong. As well when I rightclick twice so that I can pan the view it used to go back to default view via left click and it does not work either. I uninstalled everything and reinstalled and still the problem consists.
And it jumps semi frequently so that the main "flying" window deactivates and I have to click in it to steer with the keyboard. So it seems to be distracted by something...
